I've been putting together a text on ScriptUI, to a large extent to clear up things for myself (hence the title!). It's an introduction to ScriptUI, much of it very basic, here and there going into some detail. It's not a finished product, and comments, suggestions, and corrections are welcome. If you're interested, you can find the PDF file here: http://www.kahrel.plus.com/indesign/scriptui.html

In this script I'm working on (for Illustrator!), I'd like to have either a full choice of attributes in the panel, or simply "Match teeth size". I'd like something like a radiobutton at the top of the panel, as well as one instead of the checkbox -- if the panel radiobutton is selected, the attributes should be editable, but disabled when it's not.

What about this: if you check "Match teeth size" the panel with the three fields is disabled and the "Center Hole" prompt and field are enabled. Uncheck "Match teeth size" and the panel is enabled and "Center hole" disabled. That way you don't need any radio buttons.

Jeremy, can you put some numbers to that? Technical documentation on how to actually create gears is a bit hard to find, so I wrote the script to create "mirrored" hills and valleys with the exact same width. Theoretically, if you would draw them as straight lines, they'd match up perfectly. In practice, however, it seems to need a bit of 'pushing'. I don't think the script is accurate enough to design clockwork with -- but I'd sure like it to be!

Alas no... not yet, but I'm thinking about it. I'm trying to write something for InDesign that (probably) follows an entirely different method from your script, and whose results will be much more modest (at first, I'm just going for a simplistic "fortification line"). I thought if I had something of my own that works in InDesign, I might be able to work my (beginner's) way into Illustrator's object model, something I am wholly unacquainted with so far. That's why I'm replying here rather than in the Illustrator Scripting forum.
